LoRa Air Quality Monitoring System
05/06/2021
IoT Tech Put to Good Use
The degrading quality of air around us remains one of the most serious issues of the 21st century. In this project article, Dhairya designs and builds a long-range and low-power system for monitoring air quality, using various sensors and the popular LoRaWAN communication protocol.
Topics Discussed
What is the system workflow?
How to interface the sensors
How to set up the LoRa network
How to set up the dashboard
Tech Used
Dragino’s LoRa shield for Arduino v1.4 (EU868)
CCS811 gas sensor
DSM501A PM2.5 dust sensor module
Raspberry Pi SBC
Make an Interactive Sculpture with Twilio Autopilot and Airtable
In a previous tutorial, I described how to build a text-based messaging game using Twilio Autopilot, Facebook Messenger, and Airtable.
Now, it’s time to bring that data into the real world, with a creative display of all the data from Twilio Autopilot that is being stored in the Airtable database.
In this tutorial you’ll learn how you can make a small internet-connected sculpture that displays how players respond to each question stored in the Autopilot task. You’ll use a wifi-enabled microcontroller to read data from Airtable and to display the data on a small LCD screen that would be embedded in the sculpture.
